It was discovered that the Xpdf used in KOffice contained multiple securityissues when parsing malformed PDF documents. If a user or automated systemwere tricked into opening a crafted PDF file, an attacker could cause adenial of service or execute arbitrary code with privileges of the userinvoking the program. (CVE-2009-3606, CVE-2009-3608, CVE-2009-3609)

KOffice in Ubuntu 9.04 uses a very old version of Xpdf to import PDFs intoKWord. Upstream KDE no longer supports PDF import in KOffice and as aresult it was dropped in Ubuntu 9.10.
